Let the number of rows be, x.
∴ the number of plants in each rows = x.
Total many contributed by all the students = x × x = x^{2}
Given, x^{2} = Rs. 2025
x^{2} = 3 × 3 × 3 × 3 × 5 × 5
⇒ x^{2} = (3×3)×(3×3)×(5×5)
⇒ x^{2} = (3×3×5)×(3×3×5)
⇒ x^{2} = 45 × 45
⇒ x = √45×45
⇒ x = 45
∴ The number of rows = 45 and the number of plants in each rows = 45.
